13CNT01Light Detection and Ranging (Lidar)
Lidar is an active remote sensing technology that uses laser pulses to measure distances to objects or surfaces. By calculating the time it takes for each laser pulse to travel to a target and return, lidar systems generate highly accurate 3D point clouds representing terrain, vegetation, and built structures. Vertical accuracy often within 10–15 cm.
